BLOCK-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 445,928, dated February3, 1891. Application led April 28, 1890. Serial No. 349,732. (No model.)

To all whom, t may concern.-

Be it known that I, MILEY PLEAsANTroN RAWFORD, a citizen of the UnitedStates, residing at Logan, in the county of Hocking and State of Ohio,have invented certain new and useful Im provementsin Block-SignalCombinations; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

rlhis invention relates to block-signals, and

has for its purpose to provide a signal apparatus for displaying therequired signals byday and by night, and which will be compact in formand easily operated. The in'lproveinent consists ofthe novel featuresand the peculiar construction and combination of the parts whichhereinafter will be more fully described and claimed, and which areshown in the annexed drawings, in which- Figure l is side view of asignal appliance embodying my invention. Fig. 2 is a vertical centralsection ot' the signal. Fig. I5 is a sideview, parts being broken away,ot' the devices for operating the day-signals. Fig. 4 is a detail viewof theinner end ofthe lamp-operating lever and the segment having theindicating-arms. Fig. 5 is a detail View of the inner end of thedaysignal-operating lever and the segment. Fig. G is a front View of theapparatus. Fig. 7 is a perspective view of the operating-levers andtheir support, showing their connection with the connecting-bars. Fig. 8is a horizontal section on the line X X of Fig. l.

A represents aside of a block-station from which project suitablebrackets a a, to which is fastened the housing B, in which is mountedthe signal-lamp C, which is journaled in the base of the housing and ina cross-bar extending across the upper end of the housing. The housinghas side openings b I), through which the lamp may be seen from up ordown the track. The lamp is provided with two sets of dierently-coloredglasses, which are so arranged that the same color glass will comeopposite the openings b b. The lamp is rotatable in the housing, beingturned on its journals by the lever D, which is connected by rod (l andcrank-pin d with the said lamp. The crank-pin CZ projects through acurved slot e in the bottom of the housing, and the lever D is mountedon one of a series ot arms E, whichextend from the plate F. The segmentf has a series of notches which are adapted to be engaged by the pawlgto hold the lamp in the required position.` The pawl g is connectedbybar G with the hand-latch g.

The hood I-l on the front side of the housing is open on its front sideand is adapted to receive the day-signals I, which are boards or metalpainted to correspond with the colors of the glassin thesignal-'lamp-rethwhite, and green. These boards I are pivoted at theirlower ends to the sides of the hood and have depending arms t', whichare connected by bars J with operatinglevers D', which are mounted onthe arms E. These levers Dare held in a located position by the notchedsegmentsf and the pawls g2, the latter being controlled in theirmovements by the rods G and the hand-latches g3. "The several levers Dand D are provided for convenience of operation, so that the operatorneed not leave his seat. The ends of the bars J terminate in handles j,which can be readily grasped by the operator when standing or sitting.

lhe segmentf is provided with three arms L, which correspond with thethree positions of the lamp. Then thelever I) corresponds in positionwith one of these indicating-arms L, the color of light displayed may bedetermined by the color of the arm standing' opposite the said lever,the arms being painted to correspond with the color of the glasses inthe lamp.

The lamp is to be used exclusively by night and in foggy Weather, andthe boards I in clear weather and by day.

There is an extra indicator or register to Work independent from thecolor signals on the levers on the inside kof the office, so that theoperator can be doubly sure that he has the right color of signaldisplayed for approaching train by day or night, and I can make themwork on top of the building or on a post between the tracks.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1S"

l. A railway-signal comprising` a housing, signal-boards adapted to foldwithin the housingr, an operating-rodJ for eaeh board,having` a handleat its outer end, a lever Qonneeted with said rod J and having a latoh,a notched seglnenthaving radial arms in sufficient nu niber and of acolor to correspond with the signal-boards, whereby on operating,` theproper lever or rod J and bringing' it in the proper position, which isdetermined by the radial indicating-arms on the Said segment, the properSignal may be displayed, substantially as described.

2. The combination, with the housing and the lamp journaled therein, ofthe Crank-pin connected With the lamp and proj eotin sr through a curvedslot in the said housing, and
